Struct aws_sdk_appsync::client::fluent_builders::CreateResolver

pub struct CreateResolver<C = DynConnector, M = DefaultMiddleware, R = Standard> { /* fields omitted */ }

Fluent builder constructing a request to CreateResolver.

Creates a Resolver object.

A resolver converts incoming requests into a format that a data source can understand, and converts the data source's responses into GraphQL.

Implementations

impl<C, M, R> CreateResolver<C, M, R> where
    C: SmithyConnector,
    M: SmithyMiddleware<C>,
    R: NewRequestPolicy, 

pub async fn send(
    self
) -> Result<CreateResolverOutput, SdkError<CreateResolverError>> where
    R::Policy: SmithyRetryPolicy<CreateResolverInputOperationOutputAlias, CreateResolverOutput, CreateResolverError, CreateResolverInputOperationRetryAlias>, 

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub fn api_id(self, input: impl Into<String>) -> Self

The ID for the GraphQL API for which the resolver is being created.

pub fn set_api_id(self, input: Option<String>) -> Self

The ID for the GraphQL API for which the resolver is being created.

pub fn type_name(self, input: impl Into<String>) -> Self

The name of the Type.

pub fn set_type_name(self, input: Option<String>) -> Self

The name of the Type.

pub fn field_name(self, input: impl Into<String>) -> Self

The name of the field to attach the resolver to.

pub fn set_field_name(self, input: Option<String>) -> Self

The name of the field to attach the resolver to.

pub fn data_source_name(self, input: impl Into<String>) -> Self

The name of the data source for which the resolver is being created.

pub fn set_data_source_name(self, input: Option<String>) -> Self

The name of the data source for which the resolver is being created.

pub fn request_mapping_template(self, input: impl Into<String>) -> Self

The mapping template to use for requests.

A resolver uses a request mapping template to convert a GraphQL expression into a format that a data source can understand. Mapping templates are written in Apache Velocity Template Language (VTL).

VTL request mapping templates are optional when using an Lambda data source. For all other data sources, VTL request and response mapping templates are required.

pub fn set_request_mapping_template(self, input: Option<String>) -> Self

The mapping template to use for requests.

A resolver uses a request mapping template to convert a GraphQL expression into a format that a data source can understand. Mapping templates are written in Apache Velocity Template Language (VTL).

VTL request mapping templates are optional when using an Lambda data source. For all other data sources, VTL request and response mapping templates are required.

pub fn response_mapping_template(self, input: impl Into<String>) -> Self

The mapping template to use for responses from the data source.

pub fn set_response_mapping_template(self, input: Option<String>) -> Self

The mapping template to use for responses from the data source.

pub fn kind(self, input: ResolverKind) -> Self

The resolver type.

• UNIT: A UNIT resolver type. A UNIT resolver is the default resolver type. You can use a UNIT resolver to run a GraphQL query against a single data source.

• PIPELINE: A PIPELINE resolver type. You can use a PIPELINE resolver to invoke a series of Function objects in a serial manner. You can use a pipeline resolver to run a GraphQL query against multiple data sources.

pub fn set_kind(self, input: Option<ResolverKind>) -> Self

The resolver type.

• UNIT: A UNIT resolver type. A UNIT resolver is the default resolver type. You can use a UNIT resolver to run a GraphQL query against a single data source.

• PIPELINE: A PIPELINE resolver type. You can use a PIPELINE resolver to invoke a series of Function objects in a serial manner. You can use a pipeline resolver to run a GraphQL query against multiple data sources.

pub fn pipeline_config(self, input: PipelineConfig) -> Self

The PipelineConfig.

pub fn set_pipeline_config(self, input: Option<PipelineConfig>) -> Self

The PipelineConfig.

pub fn sync_config(self, input: SyncConfig) -> Self

The SyncConfig for a resolver attached to a versioned data source.

pub fn set_sync_config(self, input: Option<SyncConfig>) -> Self

The SyncConfig for a resolver attached to a versioned data source.

pub fn caching_config(self, input: CachingConfig) -> Self

The caching configuration for the resolver.

pub fn set_caching_config(self, input: Option<CachingConfig>) -> Self

The caching configuration for the resolver.
